There's a book called _Grudgebearer_ coming out which has a scene (on page 125, it appears)
in which a meeting in a Dwarf Engineering Hall is called to order with a large steel spanner
fitted with a sapphire in the center. "Obviously," quoth Tim Huckelbery (ex-Skinner 1984), who
reported it to us, "the power of the One True Gavel is spreading."
